A certain type of micro spy requires a phone subscription (or prepaid card) to be fully functional. These are the GSM spy microphones. Equipped with a SIM card, this type of microphone uses it to allow remote listening. All it takes is for the user to call the microphone to open the microphone and listen to the conversation like we're there. The GSM spy microphone will also be able to send SMS alerts to prevent a conversation from taking place. The principle is the same as for a laptop. But then, which operator to turn to?

Spy microphones and mobile operators

Fortunately, GSM spy microphones accept all operators. Before you make a subscription to an operator , you just need to find out the size of the SIM card compatible with the micro spy model you have. Nowadays, when you buy a sim card, it comes with an adapter allowing it to be adapted in several format (standard sim, mini sim, nano sim).

The choice of an operator is personal 

There are no better operators than others to equip your mike. The bottom line is that its packages are tailored to your needs, but also the use you will make of the microphone. But also includes your budget. For example, if you want to listen for days, you can turn to an unlimited plan. For listening for a few hours or a few days, you can afford a very basic and very cheap package. You can even opt for a prepaid plan.
